摘要： An eNB1-1 transmits an RRC Connection Reconfiguration message to UE2-1 to UE2-3, in which SRS parameters and an application timing parameter are set, the SRS parameters differ for each of the UE2-1 to the UE2-3 and the application timing parameter is common in the UE2-1 to the UE2-3. The UE2-1 to the UE2-3 receive the RRC Connection Reconfiguration message and recognize the SRS parameters and the application timing parameter set in the message. Furthermore, when an application timing of the SRS parameter arrives, the UE2-1 to the UE2-3 apply the SRS parameter to the SRS and transmit the SRS.

摘要： In a case where, although a radio base station (eNB 1-1) has established an SRS transmission frequency band, a serving radio terminal (UE 2-1) has transmitted, to the radio base station (eNB 1-1), an SRS by use of only a frequency band that is a part of the SRS transmission frequency band, the radio base station (eNB 1-1) allocates a downstream resource block the frequency band of which is included in the SRS transmission frequency band and further the frequency band of which is identical with the frequency band of the SRS received at the latest; then establishes, for the downstream resource block, a transmission weight based on the SRS received at the latest; and then uses the downstream resource block to transmit a radio signal.

摘要： A resource determination unit determines at least a part of an uplink part in a switch subframe as a second resource for a wireless terminal to transmit an SRS and determines at least a part within any uplink subframe as a third resource for the wireless terminal to transmit uplink user data including a DRS for a prescribed period. A transmission path state estimation unit estimates a state of a transmission path to the wireless terminal based on the DRS included in the uplink user data after the third resource is determined. A resource notification unit forms antenna directivity based on the estimated state of the transmission path and transmits a control message for notifying the wireless terminal of the determined second resource.
